WASTEWATER TREATMENT PLANT PROJECT
WWTP COST ESTIMATE
The Wastewater Treatment Plant (WWTP) facility improvements project cost estimate is adjusted up to $6.3 million. The Flume Improvement Project is complete with final costs at about $300,000, including $275,524 for Lyda Excavating, $10,431 for Otak for design and construction management, $5,425 KLS Surveying and $8,065 Shannon and Wilson for geotechnical reports and testing. This is well below the engineers cost estimate for construction. The estimate for biosolids removal is between $800,000 and $1.2 million depending on where materials are hauled – Polk County or Sherman/Wasco County (See Biosolids discussion below). The estimate for the construction of the pipe gallery, dike elevation and additional constructed improvements remains as estimated in the August 2012 Predesign report – $4.52 million – this will be adjusted by the end of the calendar year prior to going out to bid. The City Engineer and City staff direct construction management and over sight expenses will be added to the total cost through 2015.
WWTP ENVIRONMENTAL ASSESSMENT
Pacific Habitat Services (PHS) successfully facilitated the National Marine Fisheries Services (NMFS) accepted Tetra Tech’s TM (technical memorandum) on the operations protocol for operating the hyporheic infiltration allows for their concurrence that the Biological Opinion developed PHS is acceptable. The PHS Environmental Assessment and Biological Assessment are now presented to DEQ for their review under their State Environmental Review Process (See http://www.deq.state.or.us/wq/loans/docs/SERPApplicantGuide.pdf). This process meets Oregon Clean Water State Revolving Fund guidelines established to meet EPA NEPA standards.
BIOSOLIDS REMOVAL PLAN
The City continues to work with DEQ to determine what steps are required to secure an approved Biosolids Management Plan. We have also determined that the two dredging contractors have accepted work from other customers that are impacting their availability for the project in our restricted timeline – Polk County land application season is through October 15th. We have gone back to CWS to ask what their timeline is for land application in eastern Oregon – it is November 15th. At this time we are trying to secure approval from DEQ on the removal plan and approval for two sites – one in Polk County and one in Sherman or Wasco County. DEQ, Otak and City staff will meet with DEQ on this next week. Cost to haul to eastern Oregon is $32.65 a wet ton whereas cost to haul to Polk County is $25.05 a wet ton. We have increased the cost estimate for biosolids removal for planning purposes from $800,000 to $1.2 million accordingly.
The City Council and Public Works Committee met to assess their risk tolerance for initiating the dike elevation project and determined that they would accept the Public Works Committee recommendation to delay the project to a Spring 2014 start date. The City Engineer will work with our geotechnical engineer to pre approve one or more local sites as a resource for aggregate, clay and fill dirt. This activity is important in our efforts to manage cost for haul time once the general contractor charged with dike elevation is selected.
HYPORHEIC DISCHARGE INFILTRATION WWTP PROJECT
The City Council and Public Works Committee at a recent joint meeting discussed but did not form an opinion on the timing of the hyporheic discharge infiltration project. The discussion focused on whether to select a general contractor to act as the prime and have subcontractors or to select subcontractors for each discrete part of the project.

Project is complete.
OTHER PUBLIC WORKS ACTIVITY
EPA BROWNFIELD GRANT
PBS engineering has moved a variety of projects forward through the EPA and DEQ approval process. PBS developed work plans for the Rose Avenue and California Avenue projects that will yield individual Phase One Environmental Assessments for tax lots referenced as 1400, 1405 and 1499 for Rose Avenue and tax lot 700 for California Avenue. The Phase One EAs are complete for these four projects. PBS has developed Phase Two work plans for EPA and DEQ approval. We expect approval in late August. PBS also completed a Health and Safety Plan for each project and a Quality Assurance Project Plan. And lastly, PBS initiated SHPO and Cultural Assessments at both project sites – this inquiry will be completed in November as a couple of tribal contacts have requested a formal review that requires a public process.
OAWU WATER RATE
The Public Works Committee reviewed a proposed increase in the water rate for the balance of the current fiscal year. The proposal for the whole year would be a 2.81% increase from $36.00 to $37.01. I have asked Finance to develop a proposal to implement this increase in January 2014 but that adjusst it to captures the full revenue requirement.
WATER METER REPLACEMENT PROJECT
The Public Works Committee discussed information captured by Dale Webb and George Tice in their meeting with David Kanter, sales representative of Global Water. They agreed that the City Administrator should pursue a revised updated business proposal from the firm and to set a future meeting with GW sales team meeting with the full PWC. The PWC also asked that the City Administrator contact current customers of GW to get feedback from them on their performance.
WATER LINE REPLACEMENT PROJECT
Public Works staff installed a two inch water service from Bridge Street to the Snack Shack at Greenman Field.
SEWER LINE REPLACEMENT PROJECT
The City is scheduling the sewer line replacement on a property located on Second Avenue. This entails installing new sewer line in an easement, coordinating with a 3rd party plumber to stub out the lateral to the house and filling an abandoned sewer line under the house.
GRAVEL STOCKPILE AT THE VERNONIA LAKE
In a meeting with the Vernonia School District, the City agreed to allow the District to move approximately 3,000 cubic yards of mixed aggregate from the current location to the western gravel parking lot at Vernonia Lake. This stockpile is partially located on land owned by the Mitchell family who has given the City permission to store it on this site. The stockpile will be used over the next year as a source for aggregate for projects that the City has an interest in including California Avenue, Rose Avenue, and Dike Elevation projects. A floodplain development permit will be completed as a portion of the material will be stored inside the 500 year floodplain. (FYI: none of this site was wet in the 2007 flood event.)
OPRD SPENCER PARK DEVELOPMENT
The COV Parks Committee deferred to a later date the site analysis of a future restroom and picnic shelter location at the Spencer Park development. The Parks Committee did determine that the location would be on the eastern half of the former middle school footprint and has allowed the replacement park contractor to carve away the aggregate base to allow for dirt fill and grass seed to be installed this year.
SPENCER PARK DEVELOPMENT OPTIONS
Lyda Excavating is completing work that had been part of the demolition contract per agreement with the City, County and District. Lyda Excavating is working under close oversight to make sure that the imported fill material meets the requirements of the specifications. Lango Hanson landscape architect will certify the final product. Weekly progress meetings are conducted.
OPRD MASTER PARK PLAN
The City will try to wrap up this project by October 2013. A draft document will be shared with Parks Committee in September 2013.
ROSE AVENUE PROJECT
The City has been contacted by our new CDBG representative – Loren Schultz, who is the new representative for Columbia County taking over from Melanie Olson. Olson will meet with City staff on September 15, 2013, to set in motion the City’s potential application for CDBG funds for a facility on the Rose Avenue project site. This is a formal meeting that is a part of the procedural method of introducing a project to state staff.
The City is informed that the Vernonia Health Center Board received word that their application to The Ford Family Foundation was approved at $250,000, their request to the Collins Foundation was funded at $100,000, and they are in negotiation with Providence Foundation to access about $190.000.
